Poetic Genius Society - There are two membership qualifications for PGS candidates. You must score at or above the 99.5 percentile on any of the tests listed on the site, and your poetry must, at some point in the past, have been published for public consumption. This would include anything from a newspaper to a book of poems to a high school poetry magazine. In some cases, PGS will review the work of candidates who have not yet been published and consider their poetry for publication in Apotheosis. If such an allowance is made, it will meet this membership requirement.

Colloquy - Recommended for those who enjoy civil discussions. I was only briefly an active member of Colloquy in 2009, but was impressed with what I saw. "Colloquy is, to the best of our knowledge, the first high-IQ society based entirely on the Internet. It is created as a forum for the collegial sharing of thoughts, experiences, and creative expression among people of superior intelligence." To join, you must score at or above the 99.5 percentile on any of the tests listed on the site. Only scores from supervised tests are accepted for purposes of joining Colloquy.

Cerebrals Society - 99.7th Percentile (1 person in 333). Cerebrals Society is an international society for people who have a documented IQ score of at least 144 sd16 from standardized, professional tests of intelligence only. Cerebrals was founded in December 1999 by Xavier Jouve who holds a Ph.D. in Experimental Psychology. Over time the society has evolved into a growing organization which keeps providing its members with intellectual peerage and a chance to meet across distances thus reducing the sense of isolation (not at all physical) often present in varying degrees in highly gifted people. There are 222 members as of Sept. 2007. Cerebrals Society is featured on the Beautiful Mind web site in the Genius Resources section. Only scores from supervised tests are accepted for purposes of joining the Cerebrals Society.
